Digital imaging correlation of immunohistochemistry and fluorescence in situ hybridization in breast carcinoma cases with HER2 genetic heterogeneity
Genetic heterogeneity is a rare but important event in the evaluation of HER2 amplification status. In this study, the authors investigated whether HER2 fluorescence heterogeneity correlated with increased protein expression by (IHC) and/or morphologic features using image analyses.
